Recently I wrote about banking within your own community as a way to be a socially responsible investor.  If that doesn't suit you, here are some major banks which are known for their work in sustainable banking. The winners of FT's Sustainable Banking Awards came out in June but I only recently came across them.  The big winner was ABN AMRO.  Here is what the bank had to say:

“At ABN AMRO Bank, sustainability has been a defining core value since 2003 when the Group Sustainable Development (SD) department was created.

From the outset, management was convinced that SD was not about public relations but about risk management and business opportunities. With management's support, SD focused on developing environmental, social and ethical policies, ensuring their proper implementation and developing tools for business staff to recognise the importance of these issues.

With this solid foundation, the managing board recognised in late 2005 that it was time to move from risk management to business opportunity. An ambitious strategy was adopted to fully integrate sustainability into the bank’s mainstream business operations. The strategy, Accelerating and Integrating the Sustainable Development Business Agenda: from Risk to Business and from Niche to Mainstream, has empowered business managers with responsibility for realising the sustainability agenda.

Recognising the role the capital markets will play in adapting to the challenges of climate change, the Eco-Markets Group was launched in January. The group works with clients to help them finance their transition to sustainable business models and adapt to regulatory demands.”
